Stay Warm this Winter with RV Vent Insulators
Even though RV winter season has already begun, it is never too late to make improvements to your RV to make sure it is warm enough. The first thing is to invest in a secondary heat source like a RV heater or an electronic blanket.
In addition to skirting your RV as a mean of insulation for temperatures below freezing, you also can add a few vent insulators to help keep the air inside warm. They block heat and light, so you can use them in the winter to hold in heat and in the summer for extra shade.
Vent insulators are also affordable!
